[ details of the embodiment ]
Hereinafter, specific examples of the cooling body and the power storage pack using the cooling body according to the embodiment of the present disclosure will be described in more detail. The present invention is not limited to these examples but defined by the claims, and is intended to include meanings equivalent to the claims and all modifications within the scope of the claims.
< Cooling body >
Fig. 1 shows a schematic view of an example of a cooling body according to an embodiment of the present disclosure. As shown in fig. 1, a cooling body 10 according to an embodiment of the present disclosure includes a refrigerant 12, a porous flat plate-shaped heat insulating material 11, and a packing body 13. The packing body 13 serves to pack the refrigerant 12 and the heat insulating material 11 in a sealed state. The thermal conductivity of the thermal insulating material 11 per unit area was 300W/(K.m)2) And a thickness of 0.5mm to 10.0 mm.
The cooling body according to the embodiment of the present disclosure is used by being disposed between heat generating elements such as power storage units or power storage modules. By using the cooling body according to the embodiment of the present disclosure, the heat generating elements such as the electric storage unit and the electric storage module can be cooled at ordinary times, and when the heat generating element becomes very hot due to an unexpected abnormality, the heat insulating performance can be exhibited so that the heat of the heat generating element causing the abnormal heat generation is difficult to be transferred to another heat generating element.
More specifically, in a temperature range (about-40 ℃ to 70 ℃ (see non-patent document 1)) in a normal use state of a heat generating element such as an electric storage unit or an electric storage module, when heat from the heat generating element is transferred to the cooling body 10, the heat generating element can be cooled by latent heat of vaporization generated when the refrigerant 12 inside the cooling body 10 is evaporated from liquid to gas. When the refrigerant 12 evaporates, the internal pressure of the package 13 rises, and the remaining portion of the package 13 other than the portion interposed between the heat generating elements is deformed so as to expand, thereby forming a bulging portion. The expansion of the portion of the package between the heat generating elements is restricted, and therefore the portion is not deformed. When the refrigerant 12 is cooled to condense, the internal pressure of the package 13 is lowered, and the bulging portion disappears.

Meanwhile, when the heat generating element is abnormal for some reason and reaches a high temperature of about 450 ℃, the packing body 13 cannot withstand the volume expansion due to the evaporation of the refrigerant 12, so that the packing body 13 is opened. Then, the refrigerant 12 overflows from the package body 13, and the heat insulating material 11 remains in the package body 13. Therefore, the heat insulating material 11 having a high heat insulating property is interposed between the heat generating element causing abnormal heat generation and the surrounding normal heat generating elements, so that it is possible to slow down the rate at which the heat of the heat generating element causing abnormal heat generation is transferred to the surrounding heat generating elements.
Hereinafter, portions of the cooling body according to the embodiment of the present disclosure will be described in detail.
(refrigerant)
The refrigerant 12 changes its state between liquid and gas. As the refrigerant 12, for example, one or more substances selected from the group consisting of fluorine-containing organic solvents such as perfluorocarbons, hydrofluoroethers, hydrofluoroketones, and fluorine-inert liquids, water, and alcohols such as methanol and ethanol may be used. The refrigerant 12 may have electrical insulation properties, or may have electrical conductivity. The amount of the refrigerant 12 encapsulated in the encapsulation body 13 may be appropriately selected as necessary.
(Heat insulating Material)
The heat insulating material 11 has a flat plate shape and is generally substantially rectangular in shape. The heat insulating material 11 only needs to be formed of a porous material so that the heat insulating material 11 can absorb the refrigerant 12. Examples of materials that can be used as the heat insulating material 11 include woven or nonwoven fabrics formed of materials processed into fiber forms, and materials obtained by sintering particles. The material forming the heat insulating material 11 may be natural fibers, synthetic fibers formed of synthetic resin, or a material using both natural fibers and synthetic fibers.
As the heat insulating material 11, glass wool, a porous material of beads, or a nonwoven fabric is preferably used.
Examples of the glass wool include glass wool obtained by aggregating glass fibers into a wool-like form and glass wool obtained by mixing and shaping glass fibers with a binder. The glass wool is preferably formed into a sheet shape using a binder from the viewpoint of thickness stability and prevention of shedding of glass fibers. The higher the density of the glass wool, the higher the thermal insulation performance. Therefore, glass wool having a high density is preferably used. The density of the glass wool is preferably 1.5kg/m3Above, more preferably 2kg/m3Above, and more preferably 2.2kg/m3The above.
An example of the microbead porous body is a porous body obtained by sintering spherical particles of about 1 μm to 10 μm and shaping the particles into a sheet shape. Examples of the material of the microbead porous body include polymers such as polyamideimide and polyimide, and glass.
Examples of the nonwoven fabric include a fiber sheet, a net (a film-like sheet composed of only fibers), and a felt (バツト) (a felt-like fiber).
In general, in a state where a heat generating element (for example, a lithium ion battery) such as an electric storage unit or an electric storage module causes abnormal heat generation to cause ignition, the temperature reaches about 450 ℃ (see non-patent document 2) further, L iCoO is being used2In the case of the lithium ion battery of (1), the positive electrode active material is thermally decomposed at about 200 ℃ and oxygen is generated (see non-patent document 3). Therefore, for the above-described lithium ion battery, it is necessary to make the time taken for the temperature of the normal heat generating element around the heat generating element causing abnormal heat generation to reach 200 ℃ as much as possibleLong. In view of the time taken for the passenger to escape from the vehicle or the like equipped with the heat generating element such as the power storage unit or the power storage module, the time taken for the temperature of the surrounding normal heat generating element to reach 200 ℃. Through experiments conducted by the present inventors, it was found that about 70 seconds is sufficient to get 20 passengers on and off a 20-seat small bus, and about 40 seconds is sufficient to get on and off an 8-seat passenger car.

The size of the cooling body 10 according to the embodiment of the present disclosure is not particularly limited as long as it is appropriately selected according to the size of the heat generating element such as the power storage unit or the power storage module disposed adjacent to the cooling body 10.
In general, the heat generating element has a flat plate shape, and therefore the cooling body 10 only needs to be a cooling body having a main surface whose size is substantially equal to or slightly larger than that of each main surface of the heat generating element.
(packaging body)
The package 13 is formed by joining two sheet members having a substantially rectangular shape in a liquid-tight manner by a known method such as adhesion, welding, or fusion bonding, for example. Each sheet member is preferably obtained by laminating a synthetic resin film on both surfaces of a metal sheet.
